What is the difference between interchromosomic and intrachromosomic recombinations?

I did a research about them and saw some videos (e.g. this and this) with animations on YouTube. But I'm still lost between them and can't differentiate between these two expressions.

The prefix inter- means "between two or more", and the prefix intra- means "within one".

So interchromosomal recombination means recombination between two different chromosomes (for example, it normally and often occurs between each homologous paternal and maternal chromosome pair during the Prophase I stage of meiosis).

Intrachromosomal recombination would mean recombination within a single chromosome.
