Hi!

 

Im just wondering how the support for HF100 (AVCHD .MTS) is in the latest Ubuntu and latest Kdenlive?

Can I start using the Kdenlive as editor without problems, or do I have to convert?

 

Appreciate all answers!

Best Regards Fredrik

Hello,

I have a HF100. You can edit .MTS files directly, but there are some problems. When rendering, sometimes you get black frames between clips, and sometimes you get clips that are completely gray.

What I do is convert my MTS files to MPEG4 at 36000 kbps (a very high bitrate), intra-frames only, as an intermediate format. Here's the ffmpeg line:

ffmpeg -y -threads 2 -i $1 -acodec libfaac -ab 256k -vcodec mpeg4 -vb 36M -s 1920x1080 -intra -flags +ildct+ilme $1.mov

 

Cheers!

Eduardo

Hello eduardo,

when I try your ffmpeg line everything works fine, besides it seems that the film runs at half speed (like slow motion).
I used ffmpeg unter windows and VLC-Player for playback.
Do you have a clue why its not running in the correct speed ? I google a lot, but didnt find an answer

You should try editing directly OR converting to DHxNX. Transcoding is a new feature of Kdenlive 0.7.4, so you should not need to use FFmpeg. Do not use Kdenlive 0.7.3, it has poor AVCHD support. Also use a very recent ffmpeg snapshot.

What is DHyNX ?

O.K. I guess I have to update to Kdenlive 0.7.4.
Hope the update is possible without problems on Kubuntu, but I guess it is :-)

I think the codec actually called DNxHD. It's available as a custom rendering profile in Kdenlive. Go to Settings - Download new render profiles. It checks online for available new settings. You should see it there. Then it will be available in the render window under Destination - Lossless/HQ - Custom.

It makes extremely large files but they edit quite perfectly to frame accuracy and there is really no quality loss. I've tried other lossless/hq settings and they didn't work too well for me.

Generally I can edit HF100 files in 0.7.4 directly IF I don't trim any from the front of the clip. With my shooting style this is most clips. If I really need a clip cut off from the front, sometimes it will fail to render correctly or the sound gets out of sync. Then I pre-render this clip to DNxHD, import that file, and I can do whatever to it.

hi

Converting to DNxHD codec seems a good thing, because on test file i can't edit avchd file, but DNxHD yes ...

But i need to convert all my rush and i don't know how to make that with kdenlive ... i find just how to convert one file after one ...with rendering windows ... i generate script but there is two file generated and i don't know how to modify the xml file ?

how can i do for make batch conversion ?

Thanks

OK, the update was not without problems:-(

Is there anyone with a HF200 camera, would the file format be the same?
Maybe a stupid question, but I am considering buying that camera, it
is actually cheaper than the HF100 ...

Tnx Thomas

I do have this camera. The format is basically the some (a higher bitrate is possible).

@nyme: can't you just select multi files and start rendering ? Or was'nt this your problem ?

hi

i need to convert 50 files ... i don't know how to make that with rendering in batch mode .. i don't understand how the two script generated work... and i don't want open each file, convert, open next file, convert ..

nyme

I don't understand your question/problem. You can open more than one file at once (pressing Strg or Alt) and start rendering.
No script is needed.

ok, ok in fact i don't need rendering at this time, just to convert the rush directly took from camera ...

imagine i have 50 files in avchd, my goal is to convert each file with codec DNxHD, before using each files in kdenlive, just because i can't use kdenlive with avchd files ...

So i need a script to convert 50 files or more ... some months after when all will be finish, i will not need script to export the full movie ...


hope my description is better ...

thanks

Having Canon HF200, i've experienced this problem as well. It was my fault: firstly I added some clips in MTS format, and then changed the project preferences (resolution from 1440x1080 to 1920x1080). After that, all the clips had extra time in the end.

The workaround was to change preferences _before_ import of any clips.
