Bug in PowerPoint timing with transitions in video export

Question

I use PowerPoint to create small educational video's with animations for my lessons. I use "Record Slide Show" with narrations and then export the PowerPoint as video wich I share with my students.

Recently I became a fan of the morph transition, but when I keep talking while recording during a morph transition, two problems show up.

The first one, is that my voice (audio recording) suddenly stops and later on continues. And this is not what I did, during recording. I continued to speek, and now the sound pauses and resumes mid sentence. This is not what I want, I want it to display and sound just the way i recorded it.

The second problem, is that te transition adds time to the video that wasn't recorded. When the recording (including all the slides, animations and transitions) takes about 5 minutes, the video that is produced takes about 5 minutes and 50 seconds. Wich fits the amount of seconds during the transitions. 25 slides each having 2 seconds of transition time.

Answer 1

HI

Thank you for your question in this community. According to your description, your PowerPoint was suddenly interrupted while recording your voice.

I help you test it on my computer. After my test, I used the "Record Slide Show" function to record and inserted a morph into each slide. I found that the video sound I recorded would also be interrupted. However, the partition occurred when one slide was switched to the next. I think this is caused by the insertion of the morph. During the switching process, your voice will not be recorded. May I ask if you do not insert the morph , Will such problems still occur?

And, regarding the length of time, your guess is correct. If you add morph, the final video will be extended. The extra time is the time of your transition.

These are normal phenomena of PowerPoint and not that you encountered an issue. If I understand correctly, if I have a misunderstanding, please provide more detailed information to let me help you test!

Thanx For your Answer,

If this is "normal phenomena", i find them strange.

Would it not be more logical to produce a video that is as close to "record" as possible?

For one, the recording of a PowerPoint might be used in conjunction with other timed events, Like movements on a stage, or timings of a orchestra. Now, the produced video wil not have the correct time.

And secondly, i could record the sound with a different recorder, and merge the powerpoint video with the separate recorded sound. But the separate recorded sound (microphone and or software) is unaware of the extra inserted delays powerpoint wil be adding to the video.

I found that i could remove 2 seconds of each slide after recording, but that feels unlogical.

So i have a solution, separate recording and removing 2 seconds from each slide by hand.

Could i place a question somewhere, to chance this "normal" behaviour of powerpoint?

And again, thanx for the reply and kind regards,

Jos Luijten.

Hi Jos Luijten.

Thank you for your update and reply. I mentioned that this is a normal phenomenon. It is the design principle of this function. It only records the time of each slide of yours and does not calculate the duration of your animation effect. I am very sorry, if possible. , You can choose another recording method of PowerPoint

Record your screen in PowerPoint

thank you for your support and understanding!
