I think Huffyuv encoded files might be broken in latest yua. Imported a file, selected HQ then encode. Hanged for 2 seconds then Yua crashed. Happened numerous times.

I encoded to x264 and imported an MP4 of same video and worked fine with exact same settings (Interlaced, top field, D4 and F1 selected). Huffyuv generated via AVIDemux.

i doubt it has anything to do with huffyuv. more likely it is yua's handling (or lack thereof) of the input timestamps. if you give me the file then i can fix it.

yep, my mistake. the fix will be in alpha 13 due sometime this evening.

alpha 13.

- fixed crash when encoding interlaced content (thanks thethrillness)
- fixed strange audio desync from start with some source timebases
- fixed corrupt audio when encoding video from norichan running under os x 10.8.4

Awesome, that definitely did fix my issue. I noticed something else, though. Either I'm missing something, or trimming doesn't work.

My attached video is about 32 seconds. It should be around 17. I dragged the slider to the start point I wanted and chose "set start point."

The way I do it is:

1. Locate where you want to start the video. Click "set end frame". This highlights the part you don't want.
2. Press del on your keyboard or go to Trim > Delete selection.
3. The unwanted part should be removed from the video.

If you wanted to trim from the end of the video then do "set start frame" then Del.

Pressing delete didn't work, but delete selection did.

However there is still a problem, see this video.

awesome. can you describe exactly what you did to produce that? i may need to get the source file from you but for now i'll try to repro with instructions. thanks.

All I did was what Thrillness suggested. Click the slider to the start point I want, then chose "set end point" and then "delete selection" to get rid of everything before that point.

He meant the characteristics of your source video file. Like codec (h.264 or huffyuv etc), container (avi or mp4 etc).

HDL

Nah he already knows I use Norichan (and by extension, the nature of the source video).

sorry, i'm going to have to get you to upload the video. i did fix what is probably a different bug though (audio padding wasn't working in some cases).

Nate is probably figuring it out now but Yua seems to be treating the source as 29.97 instead of 59.94.

Edit: Encoded in anri and seemed fine (correctly encoded F1 as 59.94 and audio synch is fine).

alpha 14. cropping.

hit the crop checkbox and then use the mouse to drag the red borders.

also fixed a bug that was disabling audio padding in a bunch of cases resulting in desync.

hdl: unfortunately it doesn't look like i'm going to be able to do much about trimming norichan's avis. ffmpeg is decoding the audio from much earlier in the stream. maybe i can look at teaching norichan to write better avis at some point.

that info up at the top is about the source, not the output, so it's still 29.97 fps even if you switch into interlaced mode. i realize this is probably confusing; all i can say is, welcome to interlaced video.

HDL & nate, if you encode the video to Huffyuv in AVIDemux it will properly synch in Yua after encoding. That is also an option but if you have a long run then hard drive space might be an issue.

isn't avidemux unusable with interlaced video due to introduced chroma ghosting?

Not a walrus

Unless they fixed it in the last couple of months, yes.

I guess if AVIDemux is a problem you could use VirtualDub to accomplish the same task.

I don't see why AVIDemux would have a problem (and the final yua encode showed no ghosting that I could see). Surely it just serves Huffyuv frames and that encodes by itself?

nate

2013-06-13 08:55:21 pm

yeah, i don't know. it's possible that only its filters force yv12.

If it were just that easy, nate would've completed yua omega 99.0 by now.

Do you think you could add cropping in? Two reasons that I know of:

1. People transferring from VHS and getting lines at the bottom (HDL source video has it).
2. Intensity Pro leaving a 720x486 image with SD material. Allow cropping of 3 pixels from the top and bottom to leave a normal resolution.

I don't capture from VHS. The static line is from the Genesis itself, and it's always there (one of the telltale signs that it isn't played on emulator).
