deinterlace my video clips does not work?

Hi

. . . . its not converting my clips in the movie, to p . . . .

Use MediaInfo to analyse the exported clip, and post the results from the Tree view.

What makes you think the de-interlacing is not taking place on the exported video?

I suspect that what you are seeing is not de-interlacing being performed, but the result of 'pulldown' where the frame rate is changed from 30 fps to 24 fps and you see inter frame judder and possible blurring of the image.

You also get the same effect when playing 24 fps on a device that has a different framerate eg TV.

See this article for more info.

Hi

Are you saying you have set up a 24fps Progressive (ie not Interlaced = 24p) project with some 30fps Interlaced clips mixed in with 24p clips, and have selected a Progressive export template, and VPX has not de-interlaced the 30fps clips?

the deinterlace box on export is just for photos.

If you are referring to the "Apply Anti Interlace filter (reduce flickering)" selection at the bottom of the Export Template you are correct. This is badly named and is in fact a anti aliasing filter to reduce aliasing on high resolution still photos.

thanks im exporting at 24p Im not sure that the clips that are interlaced are being converted to 24p I cant get the movie to upload to amazon, they say that if you have any Interlace clips in the movie it will be rejected, so im trying to make sure im doing the export the right way to make sure its converting the interlace clips to 24p since that may be why it wont upload to amazon

It would be interesting what Media Info reports on the attributes of the file as John has suggested but I don't think it can identify that individual scenes are de-interlaced correctly. My suggestion would be to open a new project and drag the exported clip to the timeline and after going to the "Program Settings > Video Audio Tab", untick the "Automatic Interlace processing" check box and play the movie and look for any interlace artifacts (ie combing) on horizontal object or camera movements, especially on the clips that were originally interlaced.

If you are exporting as 24p then the video will be progressive. If this is being rejected by Amazon then there is another issue with the export format settings you have selected.

As Peter and I have said - we need the MediaInfo data of the exported video, without that we cannot help you.

Also what export preset are you selecting and are you changing any of the settings for that preset?

Hi

We still need the MediaInfo data of the exported video you are uploading to Amazon, without that we cannot eliminate the video as a possible cause of the problem.

Assuming you are not changing any of the export preset settings, then you are not using the recommended Amazon settings for mp4 (h.264 video) and AAC audio.

We are also having to assume that your Amazon account upload area has enough free space, the length of the video is within Amazons limit and the video does not contain any copyrighted video, any one of which can cause the upload to fail.

Hi

Thanks for the MediaInfo data, however the bottom part, where there is more data on the audio, is missing.

Can you post the missing data please.

@osensei

Thanks for the info. Based on that I can not see anything that Amazon should have a problem with. Their recommended bit rate is very high but it does not say minimum bit rate in their specifications.

Amazon is not helpful at all about the problem i cant see a problem myself but it wont upload . amazon is one of the worst to deal with they have so many people putting they movies up for free they could care less. but trying to sell throught vimeo wont even start to pay back the costs of making the movie.

Hi

Thanks for the audio data.

I agree with Peter, there is nothing wrong with the video which is in contradiction with Amazons requirements that would stop it uploading.

I assume you are using Amazon Video Direct , have you successfully uploaded to it before?
