Ipad Video Conversion Scripts

[caffrey]

Were having problems with Ipads filling up with unnecessary bluray quality movie files, also somehow they are managing to record these videos upside down (and portrait) so I created a few batch scripts for this, just thought I'd share.

The scripts fix the video, reencode to wmv at half size at a bitrate of 5k (dvd ish quality) significantly cuts down on the huge Ipad videos

 

First create a folder under c: called IpadVideos.

In that folder download a copy of ffmpeg.exe into it.

Then in that folder create 4 folders called Converted, Flip, Resize and Rotate

 

Now create 3 batch files in the IpadVideos folder.

 

Flip.bat

 

For %%A in (Flip\*.*) do ffmpeg -y -i "%%A" -vcodec wmv2 -acodec wmav2 -b:v 6000k -b:a 160k -r 25 -vf scale=iw/2:-1,hflip,vflip "c:\IpadVideos\Converted\%%~nA".wmv

 

Resize.bat

 

For %%A in (Resize\*.*) do ffmpeg -y -i "%%A" -vcodec wmv2 -acodec wmav2 -b:v 6000k -b:a 160k -r 25 -vf scale=iw/2:-1 "c:\IpadVideos\Converted\%%~nA".wmv

 

Rotate.bat

 

For %%A in (Rotate\*.*) do ffmpeg -y -i "%%A" -vcodec wmv2 -acodec wmav2 -b:v 6000k -b:a 160k -r 25 -vf scale=iw/2:-1,transpose=1 "c:\IpadVideos\Converted\%%~nA".wmv

 

So any antipodean videos put them in the Flip folder, portrait in the rotate folder and resize in the resize folder, then run the batch files, the videos will end up in the converted folder.

 

Hope it's some use

Thanks for this.

 

Would this be easily changed to convert to MP4s?

These should do what you want...

 

Flip.cmd

@echo off
pushd "%~dp0"
for %%A in ("Flip\*.*") do ffmpeg -y -i "%%A" -c:v libx264 -b:v 6000k -crf 18 -preset slow -c:a aac -b:a 160k -vf scale=iw/2:-1,hflip,vflip "Converted\%%~nA.mp4"
popd

 

Resize.cmd

@echo off
pushd "%~dp0"
for %%A in ("Resize\*.*") do ffmpeg -y -i "%%A" -c:v libx264 -b:v 6000k -crf 18 -preset slow -c:a aac -b:a 160k -vf scale=iw/2:-1 -pix_fmt yuv420p "Converted\%%~nA.mp4"
popd

 

Rotate.cmd

@echo off
pushd "%~dp0"
for %%A in ("Rotate\*.*") do ffmpeg -y -i "%%A" -c:v libx264 -b:v 6000k -crf 18 -preset slow -c:a aac -b:a 160k -vf scale=iw/2:-1,transpose=1 "Converted\%%~nA.mp4"
popd

 

WMV seems a bit of a bizarre choice.

Getting this error

 

Codec is experimental but experimental codecs are not enabled, try -strict -2

 

But added in -strict -2 after aac and its working. Thanks.

Glad to hear it's working for you now.

Were you using the latest ffmpeg.exe from zeranoe.com?

[mavhc]

you could probably integrate these ideas into my python script that searches a folder you drag to it recursively

Just checked and yes.
