Ideal video encoder setting for me and my computer?

[PacificaBren]

Hello again,

I'm digitizing Laserdiscs (so, capturing from an analog source).

The machine I'm using was built in late 2014 and it has a dual core, 2.6 Ghz Core i5 processor and 8GB of RAM. This machine does not have a discrete GPU. So, obviously it's no powerhouse.

When I look at the drop-down menu for Settings/Output/Recording/Video Encoder, I see I can choose between Software (x264), Software (x264 low cpu usage preset, increases file size), and Hardware (QSV, H.264).

Can somebody please give me some guidance as to which setting is ideal for my purposes? I want to generate really nice recordings of these Laserdiscs, but I'm worried if I tax my hardware too much, that might affect the recording quality.

Thank you for whatever advice you can give me!

Here is my most recent log file:

There is no rendering or encoding lag messages in OBS log, so it is OK, but...

I think is better to record with higher quality (and higher file size, in other words with lower CRF), and then re-encode using x264 and standalone/shared FFmpeg libs at CRF=18..22 with maximum allowed level for the target device.

Spoiler: Example of FFmpeg re-encoding to get final footage (command string)

ffmpeg -ss 9.2000 -i "C:\Temp\my_video.mp4" -c:v libx264 -vf scale=640x480:flags=area,setsar=1,format=yuv420p -profile:v high -level:v 4.0 -preset slow -crf 22 -tune film -color_range 1 -color_primaries bt709 -color_trc bt709 -colorspace bt709 -movflags frag_keyframe -c:a aac -b:a 192K -t 31.5 "C:\Temp\output_my_video.mp4"

1. here "ss" to start from 9.2 sec of the source movie (to exclude not needed parts at start);
2. video codec is from "libx264" library (most popular, free analog to H.264);
3. if movie should be exactly at 30 fps set "-r 30" here (changing framerate is not good, so it was omitted);
4. the "scale" resolution is something from this list: https://en.wikipedia.org/wiki/List_of_common_resolutions , together with "setsar" (here 1.0, so square samples/pixels are forced) it used to squeeze displayed image;
5. "area" filter for scaling down (can be used "lanczos" for sharper results);
6. profile for video is High, encoder Level limited at 4.0 - are hardware restrictions for simple old smartphone (where contend will be viewed);
7. preset is "slow" because re-encode is not running real time (you may set "placebo" here - anyway everything will be restricted by level limitations), CRF at 22 as compromise between size and final quality.
8. "tune film" - image is clear, so noise filters were relaxed (can be omitted in case of real footage from camera);
9. color range, primaries, space - for compatibility (and tagging);
10. "movflags frag_keyframe" for fast start (good for online playbacks);
11. audio encoder is AAC, bitrate is 192 Kbits/s for compatibility and good quality;
12. "t" to limit whole duration of the film to 31.5 sec (to exclude rest of the footage that may be in your source).

Note.
When using RGB source as input for FFmpeg v6.0 you need two steps: 1) RGB to YUV 444 full range; 2) YUV 444 full range to 420 limited range with chroma location position specified. I don't know other way to make it more accurate with these simple and free tools.

Of course, if you are using video editor, then you may ignore all this info.

Thank you so much for your input!

Please tell me, in case I want to experiment, what would a rendering or encoding lag message look like in the log file? Should I just search for those words?

And do you think there's any potential benefit to me choosing an encoding setting that uses the CPU more? Or should I just stick with the pure software option?

 

[qhobbes]

It would look like this but above Recording Stop
02:01:41.152: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 11174 (8.9%)
02:01:41.153: Video stopped, number of skipped frames due to encoding lag: 2851/125962 (2.3%)
02:01:41.173: ==== Streaming Stop

 

[qhobbes]

QSV doesn't use the CPU like x264 does, it has it's own hardware core.

x264 can certainly get better quality but that depends on your CPU if it can do in real time and the task.

You may want to change your OBS FPS to 29.97 to match the source frame rate.

 

[PacificaBren]

Thank you for all the info, qhobbes!

I'd had no idea what QSV was, but I just Googled it and read the Wikipedia page.

Since I'm capturing a Laserdisc while it plays in real time, am I correct in thinking the following x264 advantage over QSV wouldn't apply to my situation?

However, Quick Sync could not be configured to spend more time to achieve higher quality, whereas x264 improved significantly when allowed to use more time using the recommended settings.

Or am I misunderstanding how this all works?

Thank you again!

 

[Suslik V]

However, Quick Sync could not be configured to spend more time to achieve higher quality...

Here the "higher quality" means that encoder could pack data more effectively (into smaller space) if it had more time to "think" how to do it. In real time it almost impossible - the only thing encoder can do is to use more "thinking" units (to do same job in parallel threads). So, software encoder with powerful CPU may has room for "thinking", but hardware encoder (QSV) always runs at its maximum (there is optional low latency features, of course, but in general, the logic is same). It is because hardware encoders designed to do only encoding task, while CPU is universal and can do different tasks. Thus, some encoders for CPU was be made so that you can choose how much power from CPU it uses (to leave room for other tasks). For this purpose x264 encoder has adjustable parameter "Preset" or "CPU Preset".

When you streaming - you need to pack data into small bandwidth in real time (your have connection speed limit and server speed limit).
When you do local recording - you have much higher bandwidth (your local disk writing speed).

In most cases, all video captures done with higher quality (raw or original or master copy), then re-encoded to final video with higher compression and smaller size. Quality (or CRF parameter) plays key roll in this task.

 

[PacificaBren]

Thank you again, Suslik! Would you agree I'm better off using QSV? This is all so complicated, and I apologize if I'm being dense!

Again, the machine I'm using has just a dual core Core i5, and just 8GB of RAM. Also, it has a 5400 RPM had, and not an SSD.

If I'm understanding you correctly, I'm thinking QSV is best for my needs, since QSV is always running at full capacity, and since my CPU by itself isn't that great anyway? So x264 wouldn't have much to work with? Am I understanding better now?

Thank you, thank you!

 

[Suslik V]

No matter if there is no encoding/rendering lag messages in the log.
Keep Quality setting as high as possible.

 

[qhobbes]

Don't worry, it is complicated but we're here to help. I have a similar system (i5-3470S, 8GB of RAM, 7200 RPM HDD) so I setup OBS to replicate your setup as best I could (Base, Output and Video Capture Device set to 960x544 at 29.97 FPS) and I was able to record with x264 with no missed/skipped frames using the following settings:

I only had OBS, Task Manager and 2 file browser windows open.

I'm pretty sure QSV has a similar rate control to CRF (I think it was IQF or something like that). Before you start your LD encoding adventure, do some 5-10 minute tests with QSV and x264 to see where you can get the best quality with no missed/skipped frames for your system.

In OBS, go to View and select Stats. You can view missed/skipped frames in real time so you don't have to check the log.

qhobbes, I'm trying to find the settings in your screen shot. I went under settings/output and selected Output Mode: Advanced, but that screen looks different from your screen shot. Thank you.

 

[PacificaBren]

Wait, I see that screen shot was of your streaming settings. I am adjusting my streaming settings to match yours, even though I am not streaming anything. Does that make sense for me to do?

 

[Suslik V]

At "Recording" tab, by default, you have "same as stream" at the encoder selection field - you may want to select actual encoder instead of reusing the one from "Streaming" tab.

 

[PacificaBren]

OK, I just captured a Laserdisc at "indistinguishable quality, large file size!"

For some reason, I am not able to upload my current log file. However, I was able to view it and copy and paste the relevant things. It looks like I have no missed or skipped frames due to rendering or encoding lag. Not sure what that means about there being two frames left in the queue on closing. That sounds unfortunate.

I'm not entirely sure what the "2 frames left in the queue on closing" means but my guess is that's it 2 frames at the end of the recording and not during the recording since there was not rendering lag/overload. 2 frames at 29.97 is 0.07 seconds.

Record to FLV or MKV. If you record to MP4 or MOV and the recording is interrupted, the file will be corrupted and unrecoverable.

If you require MP4 files for some other purpose like editing, remux them afterwards by selecting File > Remux Recordings in the main OBS Studio window or enable Auto remux to mp4 in the Advanced Settings (Recording section)

You may also want to consider using the CoreAudio AAC encoder for better audio quality.

Record to FLV or MKV. If you record to MP4 or MOV and the recording is interrupted, the file will be corrupted and unrecoverable...

For his particular task it doesn't matter. It is not unique "first impression" recording or live event backup, aborted recording will need another attempt until you have made the video in one take, without interrupts.

 

[PacificaBren]

At "Recording" tab, by default, you have "same as stream" at the encoder selection field - you may want to select actual encoder instead of reusing the one from "Streaming" tab.

Today I think I might have messed up, I did a lossless capture of a Laserdisc, but I forgot to go into the recording tab and select something other than "same as stream."

But if I had selected an encoder, wouldn't that have defeated the purpose of doing a lossless capture?

I'm still having trouble uploading my previous log files, so I'll again copy and paste it here.

Could somebody please have a look and tell me whether any of my settings might have sabotaged the whole purpose of my lossless capture?

(Yes, the obvious thing is that I should look at the resulting video and decide whether it looks good, but I'm actually doing these captures for somebody else, and he's the one who will say whether the quality is good. And he's not yet had a chance to see this latest file. I honestly don't trust my own eyes for making this evaluation)

...if I had selected an encoder, wouldn't that have defeated the purpose of doing a lossless capture?

Output Mode: Simple has independent settings from Output Mode: Advanced
This is two completely different modes of OBS (not "extended" settings but completely different modes of operation).
Lossless settings will not be harmed (at least in OBS v29.1.3).

Thank you again, Suslik.

These screen shots show what I currently have selected on my Output Mode Simple, Output Mode Advanced/Streaming and Output Mode Advanced/Recording tabs or screens.

Do these all look OK to you if I'm doing a lossless capture of a Laserdisc? Is there anything in any of these settings that might detract from my image quality?

It sounds like you're saying the one does not interfere with the other, but I just want to be sure.

Thank you, thank you!
