I recently filmed a bunch of footage on my Sony FS700 camera. All of it was recorded at 1080p and 240fps.

I have imported all the file into Adobe Premiere Pro and edited the footage. Everything looks great.

However, after exporting (H.264 at 1080p), there are a few clips that don't have the smooth slow-motion effect. They look more choppy as if it was shot at 60fps and slowed to about 10%. Anybody know why this is occurring?

Here's a link to the video:

I did a quick search on the subject but couldn't really find what i was looking for so i'm reaching out to you guys for help. I shoot lots of extreme sports, rally races etc. And my current hardware that i use is Canon XA10 and Gopro Hero3. Now i need to find a affordable(max 700$) camera that can shoot 120fps/720p video. I know my hero3 can do that but it has no zoom and the picture it produces has a fish-eye effect.


The best option i found by now is Panasonic Lumix DMC-LX7. Any better suggestions?

In Adobe Premiere Elements, not the pro version, I know how to convert a clip to slow motion (select clip, choose clip -> time stretch and then enter a new percentage). But without breaking an existing clip into two or more clips how can I convert a part of a clip to slow motion and leave the preceeding and succeeding parts in regular motion?

Thanks in advance

I've offered to video tape youth hockey games (my son's team) and I want to playback the tapes to show slow-motion or stop-motion without having to pull the raw footage into my NLE (Vegas Pro). Is there a software package that will allow me to accomplish this on my laptop (at the ice arena, usually). The coach will discuss what he sees on the tape, and I will run the laptop to accomidate his coaching (simple slo-mo and reverse-motion should be all that is needed). We see this all the time with professional sports, but I don't have the resources (money) to do this for a high school team.

I have been using a Canon T2i and occasionally shoot action scenes that are planned to be editing in slow motion. I was just told by a friend that if I film at 60 fps, I need to keep the shutter speed at 120+ to be able to do the slow motion efficiently with good quality. Why is this?

Hi fellow videographers. I am relatively new to video making. I have just purchased this camcorder and very happy with the product. During my research into this camcorder I checked one video on YouTube that showed the cam producing slow motion but it did not show you how to do it. Anybody on the forum who can help me produce slow motion video?

Thanks in advance.
