Well, it is an old convention used in many video tools, that the video range is [start;end[
meaning that last frame is not included.
It is not a bug, it is intentional.

The reason it was made was the keyframes: when you cut between keyframes (which is the case in programs like Virtualdub), you select a range that starts at a keyframe Kb, and ends at Keyframe Ke.
Then the resulting range is [ Kb ; Ke [ Ke is EXCLUDED.
You can cut video and save it without re-encoding.

I don't know if that still has a meaning.

I was hoping to use staxrip to encode a bunch of frames I have stored as images in a folder. So I made a simple avisynth input script [ ImageSource("Frames%04d.png", 0001, 1199, 24, pixel_type="RGB24") ] to generate a 24fps clip from the desired range of frames and saved it as input.avs in the folder. When opening this in Staxrip it appears to open correctly and I can preview the video, but if I try an x265 encode it errors out complaining of a missing y4m header.

I can open the same script in virtualdub and export an uncompressed AVI which staxrip can encode without any problems. I could also just encode the frames with ffmpeg. But it would be nice if I could open them directly as a clip in staxrip as I was initially attempting, so if anyone has any ideas on how I could best import this frame range into staxrip without running into the y4m header error later I'd appreciate any suggestions.

Maybe it has something to do with the color format, if you right-click Filters and choose Info, which color format does it show? Maybe try another piping tool, in the x265 dialog search field at the left bottom enter pipe. Or maybe try VapourSynth (Filters > Filter Setup > VapourSynth), the image source filter of VapourSynth is more convenient.

Appreciate the suggestions, if I look at info it just says "Format : 1342177281". I tried other piping tools but didn't have any luck, but I'll look into VapourSynth now, been meaning to familiarise myself with it anyway. Guess some research into y4m is in order too. At least I have a workaround of using virtualdub first.

Thanks for the continued development of staxrip which I use all the time.

Format : 1342177281 could mean that staxrip does not understand this format, and maybe the piping tools or encoders don't understand it either, it could still be a valid format, does the preview work? The preview does a format conversion. Maybe you just need to make a format conversion. There are more ways to show the color format, and they might work better than my relative simple code:

Filters > Edit Code > Right-Click > Advanced Info > Info()

Filters > Edit Code > Right-Click > Advanced Info > avsmeter info

Filters > Edit Code > Right-Click > Advanced Info > avs2pipemod info

ImageSource("Frames%04d.png", 0001, 1199, 24, pixel_type="RGB24",
So you have a RGB24 format.
You need to convert it YUV
I would try in staxrip to insert the filter

ConvertToYUV420(matrix="Rec709")

or if your video is strictly less than 720 lines resolution:

ConvertToYUV420(matrix="Rec601")

Great, that worked perfectly, I just added that line to my input script and now encoding proceeds without errors. What confused me initially was the preview in staxrip was working fine, I guess as stax pointed out that was doing its own conversion. As was virtualdub when I processed it through there first.

Thanks to you both for your time, this is very convenient now.

Question, is the x265 in staxrip a compile of this?

It's a compile of this. Same like yours but git not mercurial.

I want to do a batch encode in staxrip. Is it possible in the settings to set a text to be appended to the end of the output files?
Like instead of -new, I want to use another text to be appended.

You can try:

Options > Paths > Default Target Name

Requires using macros.


And also:

Tools > Advanced > Event Command

Thanks. I will try.

Question for Patman. Using x265, the changing bitrate that is showing during encode, is it the current bitrate or the average bitrate? Using CRF Quality encoding.

It's the current bitrate.

I'm thinking having the average bitrate is more useful. Do any of your other versions show average bitrate? For example when you have a slow encode that is taking 2-3 days, it's good to know the average final bitrate at the moment. Having the current bitrate is not more useful than average.

Atlantis, maybe it useful to have the average bitrate and i don't know what Patman is going to decide, but in all cases the instant (current) bitrate is very important as well and must be kept.

Yes definitely like seeing the current bitrate

the avg bitrate would be easy to get:
avg kbps = current video size x 8 x video_fps / number_of_frames_written


need to adapt MB to KB

Question. Why the current bitrate is important? It means nothing. Actually it is not very useful. Here is an example. You are doing a slow encode. It is saying it is at 11236.99 kb/s. This doesn't help anything at all. You don't know if it is going up much later or if it was much lower. At any point of the encoding, even the last minute, you don't have a useful information.

On the other hand if it was the average bitrate, it is very useful. At any moment you know how the end result will be. The more you get to the end of the encoding, the more the bitrate information is accurate.

So please explain why the current bitrate is important?

I understand your concern, but in that case why ALL encoders show current bitrate if it has no meaning.
If Patman removes the current bitrate and replaces it with average bitrate, there will be many people complaining because the current bitrate is expected.
But I am not saying that the average bitrate is useless, this is why I put the formula to show it is easy to calculate.
It's up to Patman to decide.
Now, on the other hand, in Patman's builds: there is a very useful information: the estimated file size.

Hey, anyone here were using batch in staxrip? Let's say I have like 26 anime episodes in .mkv with .ass subtitles muxed in it. I want to encode it from .mkv to .mp4 with hardcoded subtitle. Were trying options > subtitles > every option and it just don't hardcode subtitles into .mp4 file. At the moment I have to open 26 stances of staxrip and in everyone manually open episode and then via ctrl + h add subtitle. Please help
