Re: BBC HD h.264 frame order judder

I've just analyzed some H.264 from tonight's BBC1-HD Olympics coverage and, yes, the encoding has changed and not in a Blu-ray-friendly way, I'm afraid. A typical GOP now looks like this: BBBBBBBIBBBBBBBPBBBBBBBP, i.e. 7 B-frames in a row. The maximum permitted in the Blu-ray spec is 3. Another reco...

Re: BBC HD h.264 frame order judder

What happens if you try to play back the recorded ts stream on your blu-ray player without touching it with Smart Cutter?

Is the judder only at the start and end of your edited ts?

When I have some spare time, I'll record a sample of BBC1-HD on my Dreambox and see if I can reproduce your issue.

Re: Smart Cutter feature request for multiple source files

In fact you could probably just use 2 SPS ID's, no matter how many clips you were joining. - When re-encoding/copying frames from file1.ts to the output, set seq_parameter_set_id= 0 in all SPS and PPS. - When re-encoding/copying frames from file2.ts to the output, set seq_parameter_set_id= 1 in all ...

Re: BBC HD h.264 frame order judder

I haven't burnt BBC HD content to Blu-ray for a while, but in the past, it would only work if I selected the "stream fix" option in Smart Cutter. Have you tried playing the m2ts file in a software player? (Windows Media Player, DivX Player, Media Player Classic, VLC or whatever.) Do you ge...

Smart Cutter feature request for multiple source files

Now that Smart Cutter can batch process files and (with the link option) merge clips from multiple input files, I have a request: If I am combining clips from 2 different files, I can't guarantee that their H.264 streams have been encoded with exactly the same parameters. Many players will fail if t...

Problems editing a ts with non-standard crop values

Please refer to the samples crop_clip.ts and crop_clip_trimmed.ts in the wavelet sub-directory of the ftp site. crop_clip.ts has been coded a bit unusually. Each frame is 1280x736 but then frame_crop_bottom_offset has been set to 4 in the SPS (meaning 16 pixels because of the chroma sub-sampling) so...

Sample mp4 which crashes Smart Cutter 1.5.4 and 1.5.5

Hi there, it's been a while since I've been on the forum. SmartCutter has been working really well for me with .ts files but just recently I've started using it on mp4 files and am having problems. See the file crash_clip.mp4 which I have uploaded to the 'wavelet' sub-directory on your ftp server. I...

Re: Blocking artifacts with v1.4.3 and v1.4.4

Version 1.4.6 works fine on my test2.ts clip. I will try some others and let you know.

Blocking artifacts with v1.4.3 and v1.4.4

I have uploaded two .ts file to your ftp site: test2.ts is the original sample clip. test2_cut_1.4.4.ts is a sample edit (frames 183 to 427) made with SmartCutter v1.4.4. The edited file has very bad blocking artifacts at the beginning of the 2nd GOP (frames 19 onwards) when played back on ffdshow t...

Version 1.4.0 - Cut ts freezes on playback

I have come across an issue with ts files edited using v1.4.0. I have uploaded samples to the FTP site under directory 'wavelet'. test1.ts is the original sample clip. (It is the same sample clip I uploaded back in November 2010 when we were debugging the duplicated GOP issue.) test1_cut_v1.3.9f.ts ...
