OK. So I have been recording episodes of various TV progs to a USB stick.

I usually do two at a time and then transfer them to PC to trim them if need be and chop the file into separate episodes.

All seems quite straightforward and it is. 😊

But I notice an odd thing...... I load the file, find the split point and delete the second episode. Then export.

This exports as a 9.87 Gb for approx 90 mins of HD.

The I delete the episode from the timeline and drag the whole file in again. Find the split and delete the first ep.

Funny thing is, when I export this section it ends up as 2.87 Gb. The picture quality appears identical. 

I use exactly the same settings for both. It's all .Mp4

Anybody any insight on this strange phenomenon?  


** I have a little piece of software that converts .Mp4 to other formats and vice-versa. If I load the big file into it and convert

it to .Mp4 (that's Mp4 to Mp4) the generated file is near to the size of the second segment exported from VideoPad.

It was actually two episodes of "Sherlock" which I took off my Sky box with a little recording gizmo that

writes the output to a USB stick. So essentially it was one contiguous file which I merely divided in two.

I sometimes record a few hours of video and edit it on the PC to trim ad breaks etc and I get extreme

 file size differences with this procedure, even if the programmes are the same length.

Not a big prob. Just thought it was a bit weird...... 🙄
