Lossless video recording issues

RetroArch Windows devices
#1

I can’t seem to get lossless video from the record feature. I’ve tried recording with FCEUMM and Genesis Plus GX and they both have compression artifacting in the outputted videos. I’m positive I had this working at some point before, but I haven’t used the recording feature since 5-10 releases back.

I’m using RetroArch 1.8.5. I don’t believe I’ve changed any settings relating to recording, but here are the relevant sections (as best as I can tell) from my retroarch.cfg file:

record_driver = "ffmpeg"
recording_config_directory = ""
recording_output_directory = "recordings"
video_gpu_record = "false"
video_gpu_screenshot = "false"
video_post_filter_record = "false"
video_record_config = ""
video_record_quality = "4"
video_record_scale_factor = "1"
video_record_threads = "2"

Below are some example screenshots. The first was taken from the Quick Menu in RetroArch. The second is a snapshot taken in VLC from the recorded video. You may need to zoom in to see the artifacts in the second image.

Any tips or suggestions will be greatly appreciated.

mmm what i see is the image streched, hard to tell differences like that.

Are there any settings I should be looking at to get raw or unprocessed output in the recording? It seems to output raw screenshots but not video.

The two screenshots above were taken without changing any settings between. I believe the video output (second screenshot) was stretched because I had FCEUMM set to 4:3, so it’s maybe not actually recording unfiltered video.

EDIT: Solved! This was the only setting I had to change:

Settings > Video > Scaling > Aspect Ratio

I had it set to “Core Provided” before. When I changed it to “1:1 PAR (4:3 DAR)” the outputted videos were just fine, proper resolution and all. Perhaps other Scaling settings would work fine as well.

I’m also having trouble with lossless recording. Got the same configurations as mentioned above.

I’ve been recording lossless videos with RA 1.7.8 with no problems for quite some time. Recently (a few days ago) I upgraded to 1.8.5 and still using the same settings all my videos now turn out corrupted. They look fine for a few seconds then shows a garbled mess all over the screen, after a few more seconds they look fine again, then repeats.

Here are 3 screens that shows the problem:

768×240

Any ideas?

EDIT: I solved it! I hadn’t updated my video codecs in a while, after installing some fresh ones the videos looks like they should. So, my bad. Sorry to take up your time. :frowning:
